TRACE-HOOK.

SPECIFICATION forming part of Letters Patent No. 265,143, dated September 26, 1882,

.To all whom it may' concern:

Be it known that I, WILLIAM K. RAIRIGH, ot` St. Petersburg, in the county ofUlarion and State of Pennsylvania, have invented certain inafter fully described, and pointed out in the tug or trace.

claims. t

Reference is to be had to the accompanying drawings, forming part of this specitication, in which similar letters of reference indicate corresponding parts in all the figures.

Figure lis a front elevation of 4one of the safety-hooks attached to the end of the trace or tug. Fig. 2 is a sectional elevation of the same, taken on the line x w of Fig. 1. Fig. 3 is a front elevation of a trace provided at the ends with the hooks. Fig. 4 is a plan view of the main part of the hook removed from the Fig. 5 is a similar view of the under side of the hinged jaw portion of the hook removed from the main part ot' the hook; and Fig. .6 is a plan view, showing the means of making the hook noiseless. g

A represents the main part of the hook; and

B represents the latch or jaw part of the hook,

which is hinged by means of the screw c upon the main part, and is adapted to close the entrance thereto, as shown in Figs. l, 2, and 3. The main part A of the hook is properly recessed, as shown at f', Fig. 4, to receive the jaw portion Band is cast with the circular chamber a., in which the coiled spring b (shown in Fig. 2) is placed. Onejgend of this spring impinges upon the projection t, formed in the chamber a., (shown in Fig. 4,) while the other end rests in the slot or openingt", madein the circular rim f, cast on the inner face ot the jaw B. The spring is thus held so as to always keep the jaw B closed against the main part A ot' the hook, except when opened by the hands for attaching the hook to or detaching it from the hame, single-tree, or trace-chain. For conveniently opening the jaw B, I cast it with the lug d upon the under side andthe lu g ci upon the upper side, as clearly shown in the drawings. For attaching the hook to the tug or trace C, I cast the main part A of the hook with the tang D, which is formed with the perforation g and larger opening, h, and is adapted to pass between the pliesof the tug, as shown in Fig. 2. The tugis formed with openings to correspond with theopeniugsgand hof the talig D. In these openings in the tug andi tang are placed the projections c e', formed upon the under side of the clamp-.plate E. The projection e is screw-tapped, as shown in Fig. 2, to receive the screwthreaded stud j, formed upon the opposite clamp-plate,F, which stud, being screwed to place in the projection c', clamps this plateF and the plate E upon the tug, and completes the attachment of the hook to the tug. The plate F is so formed that its forward end serves as a lever for screwing the stud vj ,and F, besides being efficient and convenient means for attaching and detaching the hook to and from the tug when in place upon the tug, serve also as ornaments to the tug. The outer end ot' the jaw B is formed with the hooked portion k, which, when the jaw is closed, laps upon thehooked portion k of the rnain part A of the hook, as shown in Figs. 1 and 2, and with the curved shoulder l, which entirely closes the entrance to the main part of the hook, as shown in Fig. 1, and this shoulder is overlapped by the hook k', which reaches be` low or beyond it in the manner shown, so that no movement or pressure of thehook or ot" the ring or staple placed in it will open the jaw B. The extreme end of the jaw B is slightly cut away, as shown at o, and when the jaw is closed shuts over the lip o', formed upon the main portion A, which furnishes additional se curity against danger of the jaw B being ac'- cidentally opened.

In most instances the tang B will be made so that the broad sides ot' -the hook when attached to the tug will be parallel with the sides of the tug; but in other instances the tang will be so formed that the broad side of the hook will stand at right angles to the sides ot" the tug, as shown at Ain Fig. `3. The end of the tug which has the latter style of hook is the forward end, and this hook is to be attached to the ring or staple in the hame ot' the harness. The rear end of the tug has the IOO hook with its broadv sides arranged parallel l with the sides of the tug, and is adapted to be attached to the sin gle-tree or trace-chain, as the ease may be. v

To prevent any noise or rattling ofthe hook, it is packed with rubber, as shown at s in Fig. 6. The hook is cast hollow or with a recess, s', as showrtin dottedlines in Fig. 6,21nd the strip of rubber s is forced into the cavity, where it will remain and prevent all rattling ofthe hook from contact with the single-tree or staple in the harne.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. The book cast with the recess s', in conlbination with the rubber packing s, whereby described. j

2. The main part Aof the hook, formed with zov the tang D, having the holes g and h, in combination with the clamp-plates E and F, the former being formed with the projection e and screw-tapped projection e', and the latter being formed with the screw-threaded stud j, substantially as and for the purposes set forth.

3. The combination, with the main part A, provided with the recess a and projection t' in said recess, of the jaw B, provided with the rim f, having slot i', the screw c, and the coiled spring b, substantially as and -for the purpose set forth.
